lloca.reps.tensorreps.TensorReps

class lloca.reps.tensorreps.TensorReps(input, simplify=True)

Bases: tuple

Generic tensor representations

Create a tensor representation based on the input. This can be a string representation or a list of _TensorMulRep instances.

Parameters:

• input (Union[TensorReps, str, List[_TensorMulRep]]) – The input to initialize the tensor reps. If input is a string, it is parsed to extract the tensor representations. If input is a list, it should contain instances of _TensorMulRep.

• simplify (bool) – Whether to simplify the tensor reps after initialization. Default is True.

property dim

The total dimension of the tensor reps.

is_simplified()

Check if the TensorReps is simlified.

property is_sorted

Whether the tensor reps are sorted by the order of the reps.

property max_rep

The tensor irrep with the highest order.

property mul

The total multiplier of the tensor reps.

property mul_scalars

The total multiplier of the tensor reps scalars.

property mul_without_scalars

The total multiplier of the tensor reps without the scalars.

property reps

The set of tensor reps.

simplify()

Simplifies the tensor reps by combining the same reps.

sort()

Sorts the tensor reps by the order of the reps.
